LOCKING DEVICE FOR THE 'iAnE-UP MECHANISM or ooivis.

Application filed June 15, 1920. Serial No. 383,123.

T 0 all whom it may co nceim Be it known that, I, SAMUEL C ME, a. citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Locking'Devices for the Take-Up Mechanism of Looms, of which the following isa specification.

This invention relates to looms of the type in which the take-up mechanism is actuated from a driving shaft through reversiblegear connections. These connections commonly comprise a. pair of reversely disposed bevel gears mounted on a sleeve which is splined to a vertical driving shaft and is slidable thereon to bring either the upper or lower bevel gear into engagement with a double bevel gear which in turn meshes with a bevel pinion on a shaft of the take-up mechanism.

Under normal running conditions, the

drive is through the upperbevel gear which is then in engagement with the double bevel ear.

a It is the object of my invention to provide a positive lock to hold the upper bevel gear in such engagement, so that the gears may not slip and separate during the operation of the loom. Such separation has been here-- tofore frequent, causing slipping of the teeth past each other, with much wear and breakage thereof, and causing irregular operation of the loom which itis the purpose of my invention to avoid.

With this object in view, my invention as shown herein embodies a locking device movable manually into position to engage and lock the mechanism by which the bevel gears are shifted, holding the same positively in a definite operative relation.

. ments and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of my invention is shown 4 in the drawings, in'which I Fig. 1 is a side elevation of parts of a loom embodying my improved locking device, and

Figs; 2, 3 and 4 are detail views of separate parts of the locking device.

Referring to the drawings, I have indicated a portion of a loom frame 10 having supported thereon a driving shaft 11 carrying a bevel gear 12 meshing with a similar gear 13 loosely mounted onthe lowerend of My invention further relates to arrangea vertical shaft--14 which is connected to motion of the loom '(not provided for c'onnecting thej fixed pivot 17 and'connected by 'a linklS to a bell crank 19 pivoted on the 100111 frame 10 a-ndconnected by a link 21 and pin '22- to a hand lever 23 pivoted at 24 on the loom frame. A weight 25 acts'to hold the lever and clutch in either operative or inoperative position.

A sleeve '35 is splined to the shaft'14 j is provided with upper andlowe'r gears '36 and 37. As the l v 35 is moved on, the

a shaft 14, one or the other of the gears 36 and 37 will engage and drive a'double'bevel plnlon 40 loosely mounted ona stud orbear I ing 41 on the loom side and meshing with 1 c v v constitutes the driving member'for the-takeif a pinion 38 on the end of a'sha'ft '39 which up mechanism of the loom (not shown);

An annular groove 42-is-formed in the I upper end of th sleeve 35 and the-sleeve is vertically positionedby a forked lever 43 so I pivoted at 44 on the loom frame. A link 46 is connected to the outer end 45 of the at 51 on the loom frame and having a han- All ofthe parts thus far described are or may be of the usual construction and form no part of my invention, which relates specifically toa device or attachmentforpositively locking oneof the bevel gears in driving engagement with the double bevel gear 40.

For this purpose I provide a bracket 26,

adjustably mounted on the loom frame 10 and secured in position thereon by a bolt or bolts 27 The bracket 26 has an arm or projection 28 in which a stud 29 is secured,

forming a bearing for a latch or locking lever 30. The lever 30has a transverse slot or opening 31 at the end of one of its arms the bell crank 19 previously'described.

The link 33 is preferably arranged for ad-v justment by providing a'separate head 33 improved device, the operation thereof will be readily apparent.

weighted end of the lever 23 has been Assuming that the swung to the right to stop the rotation of the shaft 14, the handle 52 of the lever 50 may then be pushed in or to the left, raising the; end 45 of the lever 4-3 and depressing the forked inner end thereof. This causes the sleeve to slide downward on the shaft 14 so that the gear 36 will engage with the double bevel gear 40. Withthe parts in this position.,-.the hand lever 23n1ay be swung. backito the osition shown in'Fil causinm the clutch lo to-engage the gear 13 and drive the shaft 14, and at the same time advancing,

the locking lever orlatch 30 so that an offset portion of thelever L3; willibe seated and firinlyheld in the slot 31.

1th the parts in this position, the lever 43 is securely locked-and upward movement oft-he bevel gear 36is effectually prevented.

Hit is thereafter desired to reverse the drive of the tal-:eup mechanism, the hand lever 23 is first moved from the position shown in Fig. l to release the lever l5 and disconnect the clutch 15, after which the lever 'may be used to reverse the engage ment of the bevel gears 36 and 37.

, \Vhilst'l have vdescribed and'shown the bestknown means at the present time, for

I effecting the object inview, I wish it clearly understood that I do not limit myself to the precise pattern and arrangement of parts disclosed, but reserve the right to make such other changes and modificationsthat may reasonably be construed as falling within the scope and ambit of the appended" claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent,-is:

1. The combination with the reverse lever of a loom take-up mechanismand thedriving" connection therefor including a clutch, a

ota locking device comprising a bearing, a

bell crank pivoted on said bearing and ha-ving a forked arm cooperating.avith said re verse lever, and a-eonnection from-the'other arm of the-bell crank to a manually operated device also controlling said clutch through which the take-up mechanism driven.

2. In a loom having a take-up mechanism, in combination, a driving mechanism therefor including reversely disposed sliding bevel gears, a hand lever 'to shift said gears to reverse the driving engagement thereof, op-: erating connections between said hand lever andsaid gears, anda-device engaging said connections between-said lever and said gears and effective to .positively'loc I said connections from movement and to thereby -posi-'r tively prevent disengagement-of said gears when in a definite; operative relation.

In testimony whereof I aifix my signature.

SAMUEL CAME.
